risugen's definition of the regex matching an insn name in
parse_config_file() is
  ^[A-Za-z0-9][A-Za-z0-9_]*$

I think we should be consistent with that. (PCRE \w isn't
quite the same as it allows a leading underscore and also
various unicode letters, but it's closer than [A-Za-z].)

(As it happens we don't have any current insn patterns
that take advantage of the ability to start with a number.
So if you'd prefer to define insn names starting with a
number to be invalid and change risugen instead that's
fine too.)
